We first got a look at 616 Fabrication’s new fat bike hubs in March 2013, which at the time were still in the prototype phase. After deciding they wanted to test the design further, 616 sent them to
a University Wheel and hub testing facility in Marquette, MI Velovations from Michigan Technological University in Houghton, MI who apparently helped develop the Thomson Dropper post as well. (video here, thanks to Dr. John Gershenson for the clarification! ). 616 followed that with another 12 months of real world testing and are now confident in saying the hubs are ready for any abuse you can throw at them. Built for the latest generation of fat bikes, these made in the US hubs are compatible with all the standards making for yet another interesting options when it comes to stretching your hubs.
Available on June 1st, 616 is currently accepting pre-orders (which are almost sold out). Tentatively called the Holy Roller, fat bike hubs will be offered as individual hubs as well as complete wheels with a number of build options. Normal mountain bike versions of the fat bike hubs will follow later this summer.
